This breed was created from Bengal Norns. The idea for Butterfly Norns came from Don, as she had created Creatures 2 Butterfly Norns years ago. The genome is based on the Chichi Norns, with the following changes:

? Extended color genes (causing the Norns keep their color for a lifetime)
? Preference for flowers (love the fragrance of flowers, produced by an accompanying agent)
? Only feel comfortable in nature
? Mutation rate of the pose genes decreased (prevents the Norns from getting limping gait mutation)
? Mutation rate of appearance genes reduced (prevents spontaneous mutations of the external appearance)
